Glad to hear you are getting some help.... the addition of a timer is a good addition but that dues not sovle my particular problem nor for other who use your transmitter for Light O Rama Shows. I do not know how big that customer base is but I was told by a Light O Rama distrubuter that your transmitters are ths best.

The code i have put together is doing exactly what we need. (light o rama users).

Additionally it now discovers the com port automatically.

I still would like an example of "TXFrqeuency" (The content of "temp") for 101.7mHz (101,700,000Hz)
